This article discusses the formation of trimesic acid (TMA) solvates with ethanol, isopropyl alcohol and dimethylformamide via liquid-assisted grinding and slurry experiments. Through the use of X-ray diffraction methods, we highlight the formation of a new ethanol solvate of TMA that completes the series of alcohol solvates observed, a temperature-induced phase transition in the isopropyl alcohol solvate between 233 K and 243 K, and a transient 1:3 solvate with dimethylformamide that mimics a previously identified dimethylsulfoxide solvate. The alcohol structures possess a TMA framework that is geometrically similar where the intermolecular energies between TMA molecules are equivalent. We have observed that increasing the length of the alcohol induces an increase in the distortion of the TMA framework to accommodate the longer alkyl tails.
